Experimental and numerical behaviour of blind bolted flush endplate composite connections

Abstract

This research presents an experimental investigation and finite element model on the performance of composite beam-to-column flush end plate connections utilising blind bolts. Previous research recommended improvements to the design of these connections if they are required to withstand a low probability high consequence earthquake of a 1-in-2500 years return period. Therefore, two full-scale sub-assemblages of cruciform composite joints were tested under static and cyclic loading. The test results were used to establish the load-displacement characteristics of the connection. The experimental results demonstrated improved stiffness and strength when compared with a previous study. Two finit..
